3. Collect data from suitable sources.
4. Clean and validate the dataset.
5. Explore patterns and relationships.
6. Visualise the main findings.
7. Interpret the business impact.
8. Recommend an action.

Beginners should also understand the four types of data analytics:

Analytics type	Question answered	Example
Descriptive analytics	What happened?	Monthly sales decreased by 10%
Diagnostic analytics	Why did it happen?	Sales declined because repeat purchases fell
Predictive analytics	What may happen next?	Demand may increase during the festive season
Prescriptive analytics	What should be done?	Increase inventory before demand rises

Focus on descriptive and diagnostic analytics first. These areas cover much of the work performed in entry-level roles.

Learners who want broader exposure can explore the best websites to learn data analytics⁠.

* Power Query
* Basic dashboards

Do not memorise formulas without using them. Practise on sales, employee and inventory datasets.

Useful Excel projects include:

* Monthly Expense Tracker
* Sales Performance Dashboard
* Employee Attendance Report
* Inventory Management Dashboard
* Customer Order Analysis

These Excel project ideas for beginners⁠ can help you practise spreadsheet analysis through real datasets. Learners who prefer video-based lessons can also explore the best YouTube channels to learn Excel.

What Should You Be Able to Do After Learning Excel?

You should be able to:

* Clean a spreadsheet
* Combine information from different tables
* Calculate business metrics
* Summarise data with PivotTables
* Create a simple dashboard
* Explain the findings clearly

Move to SQL after completing at least one Excel project independently.

Step 3: Learn SQL and Database Fundamentals

SQL is one of the most important data analyst skills. Analysts use it to retrieve and combine information stored in relational databases.

Start with:

* Databases, tables and schemas
* Primary and foreign keys
* `SELECT`
* `WHERE`
* `ORDER BY`
* `GROUP BY`
* Aggregate functions
* `CASE` statements
* Inner joins
* Left and right joins
* Subqueries
* Common table expressions
* Window functions
* Date functions
* Data cleaning with SQL

Learn SQL through business questions instead of isolated commands.

For example:

Which five products generated the highest revenue during the previous quarter?

Answering this question requires date filtering, revenue calculations, grouping and sorting.

SQL Topics Required for Data Analyst Interviews

Focus on:

* Finding duplicate records
* Calculating running totals
* Ranking products or employees
* Identifying missing records
* Comparing month-over-month performance
* Calculating customer retention
* Segmenting users
* Combining multiple tables
* Finding the second-highest value
* Using `ROW_NUMBER()`, `RANK()` and `DENSE_RANK()`

* Join multiple datasets
* Write subqueries and CTEs
* Use window functions
* Translate business questions into SQL queries

SQL should remain part of your daily practice throughout the roadmap.

Step 4: Learn Statistics for Data Analytics

Statistics helps analysts summarise data and interpret patterns correctly. Beginners do not need advanced mathematics for most entry-level roles.

Focus on these concepts:

* Mean, median and mode
* Range and percentiles
* Variance and standard deviation
* Probability basics
* Normal distribution
* Sampling
* Confidence intervals
* Correlation
* Hypothesis testing
* Outliers
* Linear regression basics

You should understand what each method means and when to use it.

For example, the mean can become misleading when a dataset contains extreme values. The median may provide a better summary in such cases.

Similarly, correlation shows whether variables move together. It does not prove that one variable causes another.

How Much Statistics Does a Beginner Need?

A beginner should be able to:

* Summarise numerical data
* Compare distributions
* Identify outliers
* Interpret correlations
* Explain sampling
* Understand statistical significance
* Select suitable metrics

Apply each concept to a dataset instead of studying formulas alone.

Step 5: Learn Data Cleaning and Preparation

Real-world data is rarely ready for analysis. It may contain missing values, duplicates and inconsistent categories.

Data cleaning usually includes:

* Removing duplicate records
* Handling missing values
* Correcting data types
* Standardising date formats
* Fixing spelling variations
* Validating numerical ranges
* Removing irrelevant columns
* Checking inconsistent categories
* Identifying outliers
* Documenting every change

For example, a city column may contain “New Delhi,” “Delhi” and “N. Delhi.” An analyst must decide whether these values represent the same category.

Data cleaning should not change valid information simply to make the dataset appear neat. Every decision should support the purpose of the analysis.

Test your Excel, SQL, statistics, Power BI, and data analysis fundamentals with this mock test and check how ready you are to move from the learning roadmap to real data analyst interviews.
